The adjustment accuracy is now +/-0.1% +/- resolution (up from +/-0.2% +/- resolution). These additional models allow our simulation products to address an even wider range of applications than before.
According to Paul Bovingdon, Product Manager for Simulation at Pickering Interfaces: “The new modules offer a simple and accurate solution for functional test systems in applications such as motor controller testing where resistive sensors (thermistors/RTDs) provide information such as temperature and altitude. We believe these new models will find acceptance in areas such as satellites and aerospace and defense projects. With the addition of more options, the product selector on our website will help you choose the right model for your application and even compare the specifications of various models.”
The 4x-297A channels can be configured as open or short circuits to simulate wiring or sensor faults, and up to 18 channels can fit in a single-slot module. Using resistor value calls simplifies software control. The module calculates the channel setting closest to the requested value and sets that value. The user can then query the module to find the actual resistor setting it uses.
A calibration cable can be connected to the module, allowing a DMM to be used to verify each channel. This greatly simplifies checking the module's calibration. Verification is performed with the UUT disconnected from the module. VISA drivers and a kernel for Windows, a universal driver for Linux, and support for other real-time systems such as QNX and LabVIEW RT are provided. Like all Pickering modules, these come with a three-year warranty.
